For crying out loud!!! Repeat after me: It's ***not*** ``wanna'',
it's ***want to*** .... ***want to*** .... ***want to***!!!!!!!
The word ``wanna'' is a colloquial contraction of ``want to''. It

accurately rendering (verbatim) an oral communication (or perhaps
for the purpose of humour).

compare 3 ratio pairwise,and get the corresponding p values,i.e: group1 vs group2 ,p value=? group1 vs group3 ,p value=? group2 vs group3 ,p value=? Which statistical test should be used? Thanks a lot for your help.
